Answer:
Cody has solved (12 × 12) = 144 problems.
Step-by-step explanation:
For every one problem that Julia completes, Cody completes twelve.
If Julia Completes x problems and Cody completes y problems, then we can write y = 12x ........ (1)
Now, given that the number of problems solved by Cody is one hundred twenty more than two times the number of problems solved by Julia.
Hence, 2x + 120 = y ......... (2)
Now, from equations (1) and (2) we get,
2x + 120 = 12x
⇒ 10x = 120
⇒ x = 12
Therefore, Cody has solved (12 × 12) = 144 problems. (Answer)
To find the interquartile range, you will list the data that is presented in the stem and leaf plot.
Find the median of the data (30.5)
Find the median of the lower half and the median of the upper half.
Subtract these two values.
The data are <u>20</u>, 25, 30, 30, 31, 40, 41, <u>49</u>.
27.5 40.5
40.5-27.5 = 13
The interquartile range is 13.
You have to get "X" by itself so you subtract 12, 7-12 is -5 so "X" = - 5
Answer:
The best option is c
Step-by-step explanation:
The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.
The number of same text book = x
Each of this textbook contains a total of 848 pages .
The total number of pages can be computed as
y = 848x
for 4 same text book
y = 848 × 4 = 3392 pages
for 3 same text book
y = 848 × 3= 2544 pages
for 7 same text book
y = 848 × 7 = 5936 pages
for 8 same text book
y = 848 × 8 = 6784 pages
for 11 same text book
y = 848 × 11 = 9328 pages
Answer:
Water left in tank is 
gallons.
Step-by-step explanation:
Given :
Capacity of tank = 9.5 gallons 
Water taken out of tank =
gallons
We have to find the water left in the tank.
Water left in the tank = Total capacity of tank - water taken out of tank
=
Taking LCM of (3,10)= 30
Solving further, we get,
Thus, Water left in tank is gallons..
